Can't replicate and operate on hashes in restricted languages -- Lua, JavaScript

Interesting... Since we are already running experiments with the old hash function, I'd like to see what we can do to make the existing method work for JS and Lua. I don't know much about Lua, but in JS, shouldn't it be simple enough to just use the 'long' npm module? Are you planning on porting PlanOut to JavaScript or Lua?

Also, + @akalicki , who might have ported some of PlanOut to JS already... :)

Yeah -- I'm specifically looking at in-browser client side applications, which are sadly limited to no node modules, and where it would be great to minimize dependencies as strictly as possible.

Not sure what the problem with using npm in a client-side apps is -- the only (public) javascript app I wrote, the PlanOut editor, uses of npm to build the dependencies (see https://github.com/facebook/planout/tree/master/planout-editor). Also, long is only one javascript file that is 8k when minified, https://github.com/dcodeIO/Long.js, so it seems reasonable to use it even if you are not using npm to compile your package. Also, of you do end up porting PlanOut to JS, I'd be happy to provide feedback and review intermediate versions.

I'm closing out this task because it's very straightforward to implement the hashing procedure in JS using the 'long' module (in conjunction with the 'sha1' module). IMO, the most straightforward way to port PlanOut to JS is to to use long, sha1, and an ES6 transpiler, running on npm. Feel free to open up another task if you decide to run with the port and could use some feedback.
